FIELD OF INVENTION

This invention relates to vessels such as water bowls for pets.

BACKGROUND OF THE INVENTION

Dogs are Man's best friend. They go everywhere we do, with rare exception. From professional service dogs, to guide dogs, to the family pet, Canis familiaris can be found nearly every place people go. Often, service dogs also go places that are dangerous or impossible for a human to go. It is imperative, for several reasons, to people to provide for the hydration and nutrition needs of domesticated dogs.

Providing for a dog can be made easier if a portable, collapsible vessel or bowl were available. A person walking a dog could attach such a vessel to a water bottle, or stuff the vessel in a pocket. Then, when it is time to feed or water the dog, the vessel can deploy, assuming a shape useful for holding kibble or water. Such a vessel would be especially useful as a water bowl, because dogs are particularly adapted to drinking water by lapping it up against gravity, rather than sipping or gulping as from a cup or bottle, where gravity assists the flow of water. Observing a dog drinking water poured from a bottle reveals significant inefficiency and waste.

Unexpectedly, Applicant has invented collapsible vessels suitable for use as a water bowl or food bowl for a dog or other pet. In some cases, a collapsible vessel according to the present invention can be folded, scrunched, twisted, stuffed, or squashed into a small, portable wad, which will then spring back into a shape suitable for holding water or food when needed for as long as desired.

SUMMARY OF THE INVENTION

Accordingly, some embodiments of the present invention relate to collapsible vessels, one such vessel comprising:

a substantially circular base having a center and a peripheral edge, comprising a plurality of ribs dispersed between the center and the peripheral edge; a side portion extending substantially perpendicularly from the substantially circular base and attached proximal to the peripheral edge; wherein the substantially circular base and the side portion define an interior surface for holding a fluid, and an exterior surface; wherein the collapsible vessel comprises a rubbery material; and wherein the vessel has a shape that is retained when the vessel is in an uncompressed state.

Other embodiments of the present invention relate to methods of making a collapsible vessel, one such method comprising:

causing a fluid precursor material to enter a mold defining the shape; curing the fluid precursor material to form the rubbery material; thereby obtaining the collapsible vessel. In such a method, the substantially circular base and the side portion are one piece.

Further embodiments relate to other methods of making a collapsible vessel, another such method comprising:

causing a first fluid precursor material to enter a base mold defining the substantially circular base having the center and the peripheral edge and the plurality of ribs dispersed between the center and the peripheral edge; curing the first fluid precursor material to form a first rubbery material, thereby obtaining the substantially circular base; causing a second fluid precursor material to enter a side portion mold defining the side portion; curing the second fluid precursor material to form a second rubbery material, thereby obtaining the side portion; fusing the side portion to the substantially circular base proximal to the peripheral edge, thereby obtaining the collapsible vessel. In such a method, the substantially circular base and the side portion are formed as two pieces that are then fused together to form the vessel.

While the disclosure provides certain specific embodiments, the invention is not limited to those embodiments. A person of ordinary skill will appreciate from the description herein that modifications can be made to the described embodiments and therefore that the specification is broader in scope than the described embodiments. All examples are therefore non-limiting.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, and some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

Where ever the phrase “for example,” “such as,” “including” and the like are used herein, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise. Similarly “an example,” “exemplary” and the like are understood to be non-limiting.

The term “substantially” allows for deviations from the descriptor that don't negatively impact the intended purpose. Descriptive terms are understood to be modified by the term “substantially” even if the word “substantially” is not explicitly recited.

The term “about” when used in connection with a numerical value refers to the actual given value, and to the approximation to such given value that would reasonably be inferred by one of ordinary skill in the art, including approximations due to the experimental and or measurement conditions for such given value.

The terms “comprising” and “including” and “having” and “involving” (and similarly “comprises”, “includes,” “has,” and “involves”) and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of “comprising” and is therefore interpreted to be an open term meaning “at least the following,” and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, “a device having components a, b, and c” means that the device includes at least components a, b and c. Similarly, the phrase: “a method involving steps a, b, and c” means that the method includes at least steps a, b, and c.

Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

In some embodiments, a collapsible vessel has a base and a side portion. The base can have any suitable shape, such as circular, and can be substantially flat, or can have a third dimension when in an uncompressed state. As used herein, “substantially circular” can indicate circular, oval, or even polygonal. The substantially circular base can have any suitable thickness, such as, for example, 1 mm, 2 mm, 5 mm, 10 mm, or 20 mm. Moreover, the thickness of the base need not be uniform. A plurality of ribs dispersed between the center of the base and the peripheral edge of the base can have any suitable geometry. In some cases, one or more ribs radiate from the center to or toward the edge. In another case, ribs form a spiral pattern. In still another case, ribs can form a grid-like pattern. In yet another case, ribs form concentric circles about the center. The ribs in certain instances impart structural stability to the base and to the vessel, yet allow the vessel and the base to be flexible. A rib can have any suitable dimensions and cross section. A rib can extend from the center all the way to the edge, or only a portion thereof. A rib can pass through the center, extend from the center, or avoid the center entirely. A rib can be straight, curved, angular, or any combination thereof. In some cases, when the vessel rests on a flat surface, one or more ribs contact the flat surface. The plurality of ribs may comprise ribs disposed on the exterior surface, that is, on the bottom or outside of the substantially circular base. Or, the plurality of ribs may comprise ribs disposed on the interior surface, that is, inside the vessel. Or, the plurality of ribs may comprise ribs disposed on the exterior surface and on the interior surface.

The side portion of the vessel extends substantially perpendicularly from the substantially circular base and attaches proximal to the peripheral edge. That means the side portion extends upward from the base, and allows the vessel to hold water, food, or another substance as desired. In certain instances, the side portion has no ribs, while in other instances, the side portion may have ribs.

The substantially circular base and the side portion define an interior surface for holding a fluid, and an exterior surface. Together, the substantially circular base and the side portion achieve a shape that is retained when the vessel is in an uncompressed state, and both the base and the side portion have the flexibility to bend and fold into any desired smaller volume. That shape can represent any suitable shape, such as, for example, an open-top cylinder. It can be advantageous, in some embodiments of the vessel, for the sides to be just sturdy enough to maintain their shape when filled with water, but collapse if the vessel is lifted to be poured. In other embodiments, the side portion is sturdy enough for the vessel for water to be lifted and poured without the side portion collapsing and spilling water. The side portion, therefore, can be of any suitable thickness and flexibility. For example, the side portion can have a thickness of 1 mm, 2 mm, 5 mm, 10 mm, or 20 mm.

Additional embodiments provide collapsible vessels further comprising a plurality of side ribs disposed on the side portion. Such side ribs can offer additional structural support for the side portions, while retaining significant flexibility so the vessel can folded, bent, and scrunched into a smaller volume for storage and portability. Any suitable geometry can be used for the plurality of side ribs. For example, in some cases, the plurality of side ribs comprises side ribs arrayed substantially perpendicularly to the substantially circular base. In other cases, the plurality of side ribs may comprise side ribs arrayed at an angle other than 90° to the substantially circular base. The side ribs may be straight, curved, angular, or a combination thereof. In addition, the plurality of side ribs may comprise side ribs disposed on the exterior surface, side ribs disposed on the interior surface, or a combination thereof.

A collapsible vessel can be made of any suitable rubbery material. Such a rubbery material may be, for example, tear-resistant, flexible enough to bend, fold, and scrunch, and yet resilient enough to retain a shape in an uncompressed state sufficient to hold a volume of water or an amount of kibble or other food. In some cases, the rubbery material comprises natural vulcanized rubber, synthetic rubber, or a combination thereof. In further cases, the rubbery material comprises ethylene propylene diene monomer-derived synthetic rubber, styrene butadiene, polychloroprene, polyurethane, styrene ethylene butylene styrene copolymer, silicone, and combinations thereof. It may be pointed out that certain instances do not include any metal, wood, stone, or inflexible plastic. Other instances allow for a reinforcing structure, or decoration, or both, provided by metal, wood, stone, ceramic, or inflexible plastic, or a combination thereof. The collapsible vessel of certain embodiments contains a rubbery material that is suitable for contacting a fluid to be consumed by a mammal. That means that the fluid to be consumed does not leech or transport from the rubbery material to the mammal one or more substances that would be toxic to the mammal, or in amounts that would be toxic to the mammal. In some cases, that would mean the interior surface, at least, comprises a rubbery material that is “food-safe.” Among other suitable rubbery materials, ethylene propylene diene monomer-derived synthetic rubber may be mentioned in particular.

The rubbery material can have any suitable physical properties. For example, tensile strength can be less than 100 pounds per square inch, 100 pounds per square inch, 500 pounds per square inch, 1,000 pounds per square inch, 2,000 pounds per square inch, 5,000 pounds per square inch, or greater than 5000 pounds per square inch. In some cases, tensile strength ranges from about 500 pounds per square inch to 2,000 pounds per square inch, or is about 1,000 pounds per square inch. Elongation at break or onset of plastic deformation can be less than 100%, 100%, 200%, 300%, 400%, or greater than 400%. In certain instances, elongation ranges from about 200% to about 400%, or is about 300%.

A collapsible vessel may further comprise at least one decorative impression. A decorative impression comprises an area of the side portion, for example, that contains a color, a design, lettering, a picture, or any suitable artwork. The decorative impression can be printed on the collapsible vessel, molded into the material of the vessel, or fused onto the vessel such as with glue or other adhesive after the vessel has been molded and cured. Any suitable material can be used for the decorative impression. In some cases, the decorative impression comprises an additional rubbery material different from the rubbery material of the collapsible vessel. In other cases, the decorative impression comprises an adhesive-backed thin film (a “sticker”) applied to the exterior surface of the side portion, for example.

Other embodiments of the present invention relate to methods of making a collapsible vessel. Any suitable method can be used to make a collapsible vessel, employing known techniques and yet-to-be-developed techniques. One such method comprises

causing a fluid precursor material to enter a mold defining the shape; curing the fluid precursor material to form the rubbery material; thereby obtaining the collapsible vessel. Any suitable fluid precursor material can be used. For example, molten elastomerized thermoplastic can flow into a mold having the desired shape of the vessel in an uncompressed state. Alternatively, unvulcanized natural rubber, one or more monomers, and synthetic rubber precursors, alone or in combination, can be introduced into the mold, and then cured such as by heating at a suitable temperature for a suitable time, such as is known in the art. Mold release agents and other additives can be employed.

Further embodiments relate to other methods of making a collapsible vessel, another such method comprising:

causing a first fluid precursor material to enter a base mold defining the substantially circular base having the center and the peripheral edge and the plurality of ribs dispersed between the center and the peripheral edge; curing the first fluid precursor material to form a first rubbery material, thereby obtaining the substantially circular base; causing a second fluid precursor material to enter a side portion mold defining the side portion; curing the second fluid precursor material to form a second rubbery material, thereby obtaining the side portion; fusing the side portion to the substantially circular base proximal to the peripheral edge, thereby obtaining the collapsible vessel. The first rubbery material and the second rubbery material can be the same or different, and both employ any suitable rubbery material such as those described herein.

When desired, a decorative impression can be introduced to the collapsible vessel according to any suitable method. In some cases, a decorative impression can be included in the mold of the vessel. Sometimes, a mold can comprise a removable portion that forms the decorative impression, so that different vessels can easily be formed with different decorative impressions. Color can be imparted to the decorative impression in a suitable manner. For example, a colorant can be introduced into the mold at the decorative impression. Or, paint, ink, or an adhesive-backed thin film (“a sticker”) can be applied after molding and curing.

Collapsible vessels of the present invention can be used in any suitable manner. For example, a collapsible vessel can be folded and scrunched, and bound to a plastic water bottle such as by a rubber band or cord, and accompany a person and her dog on a walk. At some point in the walk, the collapsible vessel can be unbound from the bottle, deployed on the ground where the vessel assumes its uncompressed shape, and water from the bottle can be poured into the vessel for the dog to drink. When the dog is finished, the water could be poured out, the vessel folded, scrunched, and bound to the bottle again for the walk to resume.
